Black Sabbath School for Girls?

I had a really strange dream this morning - not really a nightmare, but a weird and funny one. I dreamt I was attending a school that was somehow financed by Black Sabbath, and part of Ozzy's business empire. So that meant that the dealings of the band and their production work, though not their actual shows, would sometimes interfere with the school (Ozzy running a girlschool? lol) During an houir of wooden and metal handicraft, I pointed out to the teacher that the machines we used were so loud, and someone stated it was because they were the model Sabbath would be using on stage, with proper amping (Sabbath were never an industrial sound band, were they?)

To try to get rid of the rough sound I penned a letter to the Headmaster of the place, who told me and a number of other kids that "this is not unique, Black Sabbath Inc. are in fact doing sound testing for their equipment in many different places, with many kinds of methods". Among other things, they were supposed to have about twenty-five vacant lots all over London where they staged pull.-downs of houses to be able to try out different kinds of machines, sounds and stage effects...
